MDKSA-2003:113

Problem description

A vulnerability was discovered and fixed in screen by Timo Sirainen
who found an exploitable buffer overflow that allowed privilege
escalation. This vulnerability also has the potential to allow
attackers to gain control of another user's screen session. The
ability to exploit is not trivial and requires approximately 2GB
of data to be transferred in order to do so.
Updated packages are available that fix the vulnerability.
